If you want to write tip for different peoples, does bot sends pm to all at same time?If yes, it can use used to do contest/giveaways like

" Post your entries, I will send money. First one to accept it will win "

Not the same time because I have to wait for at least 20 sec to send pm after pm, but if you have a pretty large amount you can say the first 20 to accept, the pm delay should not have a lot of effect.
